bike runs alot better when cold!

my bike runs alot better when it is cold! it pulls miles better! when its warm it pulls but not as gd!
it is not the auto choke as it is mannuel choke spec is

wow whats wrong with u?

and my bike also runs better when its cold wobbly gave me an explanation as to why before cant remember but yee its kind of obvious why

 

Is it something to do with the belt being tighter when cold, and slacker when warm?? Or am i being a twat lol?

 

if i remember correctly, its because the air is colder and more dence when entering the crank case

 

Yeah something to do with the air density

And its the reason AC's will tend to be slightly slower in the summer.

 

what a shit answer.

cold air is more dence and therefore contains more oxygen, more oxygen means bigger/better combustion (with correct fueling). more combustion means more horsepower.

 

is it me or is that not what he was getting at ?

he didnt say cold air is better but ment that by saying they worse in summer or is it me being retarded :wtf: :w00t:

 

yer something to do with air density?

what kind of retarded answer is that?
if your going to answer a question, answer it so that the reader fully understands the answer and the reason behind the answer.

if you cant do that, then dont reply in the first place?

 

dont want to start another argument :rofl:

but he was only saying what he knows.

am sure the person wanting to know could have worked it out from what he said but any dont want another argument think we had enough for now.

 

not looking for an arguent either,

but you saying im sure the reader can work it out, is completely wrong,

its like me saying, a mercedes E class uses sensotronic brake control, electronic brake management with no physical imput from the driver.

you going to explain to me how that works if you dont no?


there's no need for a half hearted answer what so ever. thats all

 

As air temperature drops its density increases.

The rate of change is about a 1% increase in density for every 6 deg F of temperature reduction...

Also remember a carb meters fuel by virtue of the volume of air passing through it....in other words its a volume sensitive device...

changes in air temperature can cause fluctuations on carburetted engines...

especially on 70cc engines with 21mm carbs on them, which suffer a little bit with a weak signal over the main jet due to the large size of their internal diamater (minor did briefly explain this in another post)

EDIT: wax head also recently explained (with diagrams) how a carb works!!
worth looking for the post...

A smaller carb has a stronger signal at the main jet and carburates more cleanly hence better throttle response and more low to mid range torque...

but the small internal diamater can restrict the top end power (strangle the engine)

fitting a bigger carb eliminates this at the cost of throttle response etc because of the poorer signal at the main jet...

but as i mentioned earlier...very cold air is denser in oxygen and causes a stronger signal at the main jet makeing it issue more fuel...hense more torque and throttle response= much better accelleration and pick up

stevo is also right about packing denser air into the combustion chamber
makeing more power....but the carb metering explanation is the main reason on a small capacity scooter engine!!

anything you dont understand...feel free to ask!!!

or you could allways invest in a good tuning book or 2!!!

Heres a few ive got lying around the house

 

answer

now thats what i call an answer

 

yeh was a good answer, but fuck me all the others were trying to help aswell, its a forum, we all have views/answers!! (aimed at stevo!)

 

lmao mate your a PRICK mate i was trying to help and wobbly told me something along those lines once so I was just saying wat I know I dont see what was wrong with that sorry I'm not a fuckin nerd like you but sheez how would you like it if no one replied in topics and it was just you minor wobbly and terr0. Yeah great fun you cock get out and get a life.

Possibly going to get banned but im not going to get gunned down on a forum jus for trying to help someone.

 

thing is it was 80% right. just didnt explain everything done to perfection but from what he said it obviously made it abit clearer to the guy wanting to know was better than n0 advice ?

if everthing had to be bang on then noone would post apart from thr big dogs and wouldnt that be boring,

my opinion unk:

 

lol terr0 you can post what you want at the end of the day mate really doesnt bother me in my eyes that wasn't bad avice as i got told this by one of you and now one of your friends decides to try and gun me you think you will get involved aswell so from now on im not posting here just going to view posts not that anyone gives a fuck jus saying theres not much point posting if you can't even try and help others is there? its a forum afterall if you want 100% accurate answers why dont you just delete this forum and make a FAQ page with every single scoot answer in the book.
